The CT Collective was started by Michael Klobuchar using cassettes (remember them?) The group members contributed music by mailing a master tape which was distributed to the members as a CD. No one got paid for any of this! I found it a great creative stimulus, creating music to fit the theme and hearing how others interpreted it.
This was a collection of one minute pieces without any other rules – out of my comfort zone with 5/4 time and dadgad tuning! Aimed to give the melody a flutey feel… my track “My Newt” is available here.
